Does a government entity which is sponsoring a job fair have to provide a fair sign language interpreter for the employee of an organization that will represent the organization at the fair so that the employee can communicate with fair-goers?

There is an important distinction between fair-goers and fair participants that dictates who must provide the sign language interpreter. The government entity must provide an effective means of communication (auxiliary aids) so that entities who will be participants (exhibitors) can receive support and services to participate in the fair related to set-up, display, break-down etc. There is no obligation on the part of the government entity to provide a sign language interpreter for the employee of the exhibitor. The provision of a sign language interpreter for the employee is a workplace accommodation issue and the responsibility lies with the organization to provide an effective means of communication so that the employee can do his/her job.
